“…Since PEs plasticizers are not chemically bound to PVC, they also easily filter into aquatic ecosystems among others (Olkowska et al, 2017;Chen et al, 2018;Kashyap and Agarwal, 2018). PEs enter the environment through several pathways including losses during manufacturing processes and weathering, leaching or volatilization from final products (Kashyap and Agarwal, 2018;Das et al, 2021). Several aquatic ecosystems such as lakes (Lee Y.-M. et al, 2019;Gao X. et al, 2019), wetlands (Gao and Wen, 2016;Wang et al, 2017), marine environments and rivers (Arfaeinia et al, 2019;Zacharia, 2019;Ai et al, 2021;WHO, 2021) have been characterized as highly polluted by PEs among other organic pollutants.…”

“…DMP, DEP, DBP, BBP, and DEHP are the most dominant PEs in both aquatic sediments and waters with some DEHP concentrations frequently exceeding the annual average environmental water (freshwater and marine) quality standard of 1.3 μg/L (EU directive 2008/105/EC) (UNEP, 2020). The high number of recent PEs studies and PEs detection rate in Asia could probably be attributed to the higher volume of PEs produced and used in these environments, because of the absence of stricter regulations on usage of the PEs designated as priority pollutants unlike in developed countries of Europe and United States of America (UNEP, 2020; Das et al, 2021;Li et al, 2021). However, most values do not exceed the trigger threshold values of 5,100, 1,300, and 64.6 μg/L for DMP, DEP, and BBP respectively for protection of about 80% of aquatic species proposed by Australian and New Zealand guidelines (Net et al, 2015a).…”

“…In aquatic ecosystem, some PEs are stable, persistent, and resistant to natural degradation, hence previous studies demonstrated the feasibility of PEs from contaminated water to bio-accumulate and bio-magnify in the food chain Sun et al, 2015). Albeit, biodegradation is the dominant route for PEs degradation in the environment (Staples et al, 1997a;Chang et al, 2004;Xu et al, 2020;Das et al, 2021). Documented studies have reported that marine microalgal (Gao and Chi, 2015) and some microbial species possess the capability to degrade PEs (Ren et al, 2018;Yu et al, 2020), with microbial degradation considered the main route of PEs transformation (Yu et al, 2020).…”

Microbial degradation is however, generally affected by external environmental factors and typical lack of specific degrading bacteria in the aquatic ecosystem, which in turn makes PEs degradation difficult under natural conditions, hence their long half-life, that range from a few years to several hundred years (Fang et al, 2018;Das et al, 2021;Zhang et al, 2021). Interestingly, recent studies confirmed the ability of Bacillus mojavensis B1811 (Zhang et al, 2018a) and Paracoccus kondratievae BJQ0001 bacterium (Xu et al, 2020) to have high efficiency for the degradation of PEs.…”

“…Although both the cyanobacteria and freshwater algae are capable of producing DBP or monoethylhexyl phthalate (MEHP) under natural conditions, which can then be released to aquatic ecosystem, anthropogenic activities pollution such as agricultural pesticides, industrial effluents, commercial wastewaters, landfills (Zhang et al, 2021) and householdelectronic and solid wastes (Zhang et al, 2019) all act as the main avenues of PEs into these aquatic ecosystems. Due to their high octanol-water partition (K ow /logK ow 25 ) (1.61-9.46) and low vapor pressures (Pa 25 ) (1.84 × 10 −6 -0.263), most PEs entering the water environment have extremely low volatility hence can easily migrate into various water bodies and enter aquatic organisms (Net et al, 2015a;Das et al, 2021;Zhang et al, 2021). Since the value of K OW increases with increasing alkyl chain length, this results in increased hydrophobicity for the higher molecular weight PEs, hence their higher sorption to organic matter (Das et al, 2021;Zhang et al, 2021).…”

Phthalate esters (PEs) are by far the most produced and extensively used synthetic organic chemicals with notable applications in many industrial products such as vinyl upholstery, adhesives, food containers, packaging materials, printing inks, adhesives, cosmetics, paints, pharmaceuticals munitions, and insecticides among other. PEs have long been recognised as ubiquitous organic pollutants of prime environmental concern, with urbanisation amongst the main cause and source of these compounds. Due to their notoriety, these compounds are known to pose devastating effects to living organisms including humans. The presence of PEs and their metabolites in the aquatic ecosystems is of concern primarily due to their endocrine disrupting and carcinogenicity properties. Several research studies have reported prevalence, exposure pathways, toxicity, and impacts of PEs in aquatic ecosystems and humans. Their principal routes of exposure could be direct or indirect, of which the direct route include contact, eating, and drinking contaminated foods, and the indirect route constitute aerosols, leaching and other forms of environmental contamination. PEs find way into water systems through means such as effluent discharges, urban and agricultural land runoff, leaching from waste dumps and other diffuse sources. High-end instrumentation and improved methodologies on the other hand have resulted in increased ability to measure trace levels (μg/L) of PEs and their metabolites in different matrices and ecological compartments of water or aquatic ecosystems such as lakes, oceans, rivers, sediments, wetlands and drinking water samples. In light of the above, this article provides an informed and focused information on the prevalence of phthalate esters in aquatic systems and related effects on living organisms and humans. Furthermore, techniques that have enabled the extraction and analysis of these PEs in aquatic samples are also explained. Future research outlooks and needs are also highlighted in this manuscript. This information will be used to better understand their temporal and spatial distributions in the aquatic systems and aid in devising prudent means to curtail their ecological footprints.

Removal of Phthalates from Water by Unconventional La‐based/WO₃ Photocatalysts

et al. 2022

La 2 O 2 CO 3 -WO 3 composites were here proposed as unconventional photocatalysts for the removal of phthalates in water. The high sorption properties of the lanthanum dioxide carbonate allowed a strong adsorption of the phthalates which facilitated the following solar photocatalytic degradation, further boosted by the addition of small amounts of WO 3 (1 wt %). On the contrary, a higher content of WO 3 had a detrimental effect due to the covering of the surface sites of La 2 O 2 CO 3 that inhibited the adsorption process. This double mechanism of strong adsorption-photocatalytic oxidation led, after 6 h of solar irradiation, to 67 % and 63 % dimethyl phthalate and di(2ethylhexyl)phthalate degradation, respectively. The phthalates were degraded to less persistent pollutants that, however, were completely removed after 9 h of irradiation. The La 2 O 2 CO 3 -WO 3 system appears promising for its application in the removal of the emerging contaminants from water.[a] E.

BACKGROUNDMost studies have focused on the degradation of endocrine‐disrupting chemicals using persulfate activation processes. Therefore, the current study compares various sulfate radical activation processes in an aqueous solution of a mixture of diethyl phthalate, butylparaben and bisphenol A that are present in water and wastewater. The effects of initial persulfate dose and pH variation, the effect of concentration of target endocrine‐disrupting chemicals and degradation efficiency under various processes were studied. Additionally, the toxicity and cost estimation of the systems were also examined.RESULTSThe results showed pseudo‐first‐order kinetics with maximum degradation efficiency of 99% for 1 mg L−1 at pH 7, 2.5 mmol L−1 persulfate dose, 450 W power in 60 min for UV‐activated persulfate oxidation process. A quenching experiment highlights the dominance of both sulfate and hydroxyl radicals in the degradation of mixtures of diethyl phthalate, butylparaben and bisphenol A in an aqueous solution. The transformative products identified using gas chromatography–mass spectrometry were monohydroxylated structures that decompose to form organic acids, indicating efficient degradation capacity with minimal toxicity. Further, the sono‐activated persulfate oxidation process was found to be cost‐effective at 1 mg L−1 with 95% degradation efficiency.CONCLUSIONIt is concluded that an increase in the concentration of target compounds decreases the efficiency of degradation under various activation processes. pH 3 and pH 7 favor thermal and sono‐activated and UV‐activated processes, respectively. Toxicity evaluation shows minimal harm to non‐target species Daphnia magna for all activation processes. These findings can be useful for on‐field application for the degradation of chemicals in mixtures. © 2023 Society of Chemical Industry.
